The Microchip Technology ATSHA204A-MAHDA-T is a specialized integrated circuit designed for secure authentication and encryption applications. It features hardware-based key storage and supports secure symmetric authentication operations for both host and client devices.
Key technical specifications include the superior SHA-256 hash algorithm with MAC and HMAC options, a 256-bit key length with storage for up to 16 keys, and a guaranteed unique 72-bit serial number. The device also incorporates an internal high-quality Random Number Generator (RNG).
For data storage, it offers 4.5 kb of EEPROM for keys and data, along with 512 bits of One-Time Programmable (OTP) memory for fixed information. Communication interfaces include a UART-compatible High-Speed, Single-Wire Interface and a 1 MHz I2C interface. The operating supply voltage ranges from 2.0V to 5.5V, with a communications voltage range of 1.8V to 5.5V. It boasts a low sleep current of less than 150 nA.
This authentication chip is packaged in an 8-UDFN (2x3) surface-mount package, making it suitable for applications in networking and communications. Its features support secure download and boot, ecosystem control, and anti-cloning functionalities.
